HKG
HKG-YVR on a Boeing 777-300ER (New entertaiment)

I realised that those entertaiment you see inside CX website is avaible on ALL planes but on those New plane (e.g. 777-300ER) they have extra entertaiment in flight.
LIke the music, not only the have radio channel but they also have about 888CD's to let you choose from.
Games too while the old cabin dont have them

You can watch CX entertaiment that i recorded at www.youtube.com/sealalula
